Interest rates have gone up quite a bit recently and are expected to continue to go up. Rates are currently higher than they've been in many years. Bad news for borrowers. Great news for savers.
Sadly, bank interest rates are often only around 0.20% per year, which is, frankly, ridiculous!
Alternatives?
Consider a CD, but before you do investigate the penalty for early withdrawal in case you need the money for an emergency before the CD expires.
Another alternative is a money market fund at a brokerage firm like Charles Schwab, Vanguard or Fidelity. These money markets have virtually zero risk. I can't speak for all of them, but the one with Schwab (Symbol: SWVXX) is available to you in just 1 business day with no penalty whatsoever should you need the money. The minimum investment is only $1. Oh yeah, it is currently paying 4.95% and that rate is likely to go up over the next several months as the Feds continue to raise interest rates.
So, a million dollars in cash could be earning you almost $50k a year. Not too shabby!
If your bank has been paying you a tiny rate of return and hasn't openly told you that there are ways to earn SUBSTANTIALLY MORE MONEY, you ought to consider that carefully before you have future dealings with the bank.
